Trivia

Armored enemies will often attempt to flank players in Co-op Arena, typically during siege. It is highly advised to check behind you and also check around corners to see if one is approaching.

The arm and leg armor of an armored enemy is much weaker compared to their chest and back armor. If you obtain a PAK-80, it only takes about 8 shots to the leg/arm to kill one, making it a highly effective strategy to eliminate them with little effort.
